There are two types of duplex communication systems : full-Duplex and half-Duplex.
2.
All these three standards define both full-duplex and half-duplex communication.
3.
The two devices that communicate simulate full-duplex communication by quickly turning the link around.
4.
Circuits were character oriented and the network was oriented towards interactive character-by-character full-duplex communications circuits.
5.
Push-to-talk cellular calls similarly provide half-duplex communications while one person transmits, the other ( s ) receive.
6.
These systems claim symmetric and full duplex communication in excess of 1 Gbit / s in each direction.
7.
The main difference is that it uses a single two-way communication data line for half-duplex communication rather than separate transmit and receives lines.
8.
In contrast, a PCI Express bus link supports full-duplex communication between any two endpoints, with no inherent limitation on concurrent access across multiple endpoints.
9.
A perhaps more efficient transport for real-time messaging is WebSocket, a web technology providing for bi-directional, full-duplex communications channels over a single TCP connection.
10.
Business frequencies in the UHF range are also licensed in pairs to allow for repeaters, though taxi companies usually use the pair for duplex communications.
